Abstract EN

Onions are considered one of the most important Egyptian vegetable crops, as their production is estimated at 1936 thousand tons, and the quantity consumed is about 1547 thousand tons, and the amount of onion exports is about 356 thousand tons, for the average period (2000-2019).

In most countries of the developed world because it helps reduce waste while maintaining the quality of the product and Egypt has authorized the irradiation of all kinds of spices and medicinal herbs And dried onions at the end of the nineties of the last century and at the beginning of the current century, legislation was issued in March 2002 permitting the irradiation of fresh potatoes, onions and garlic crops in order to prevent planting.

time of harvest, and germination results in a loss of weight and nutritional value.

It aims to show the effect of radiation use on the production and export of onions by indicating the quantities produced and exported, and the most important importing markets for Egyptian onions.

The results of the research that the annual increase in the quantity of onion product is about 7.4% of the average of 1936 thousand tons, while it is estimated at 8.4% of the average consumption of about 1547 thousand tons, while it is estimated at 10.5% of the average loss of 245.6 thousand tons, with a value of about 14.8 % and the annual increase in the amount of exports is estimated to represent about 5.1% of the average of about 356 thousand tons.

The Saudi, Russian and Gulf markets are considered among the most important importing markets for Egyptian onions.

Onions are preserved and stored in Egypt on the cold, and the amount of waste in the case of storing onions for six months in this way is estimated at 22-30% of the produced and stored quantity.

In contrast, the amount of loss during the same period is about 13.2-17%, and to show the difference between the use of the two methods, we get the difference between The two methods calculate the amount and value of the loss for the difference in the case of the minimum, which is estimated at about 247.5 thousand tons, and its value is about 291,290 thousand pounds.

In the case of the maximum, the difference in the amount of loss was estimated at about 366 thousand tons, with a value of about 430,314 thousand pounds, for the average period (2015-2019).

This confirms the importance of using irradiation for the onion crop to reduce losses.
